As a estimation we are told £3 is €4. Convert £25.50 to euros €
Answer:
£34
Step-by-step explanation:
→ Find how euros is in a pound
£3 = €4
£1 = €1.33
→ Multiply the euro by 25.50
1.33333 × 25.50 = £34
Answer:
€34
Step-by-step explanation:
First you'll want to find out how much £1 is.
Since we know £3 is equal to €4 we can:
divide £3 by 3 = £1divide €4 by 3 = €1.33So, £1 = €1.33
With this in mind, we can find out what £25.50 is:
£1 x 25.50 = £25.50€1.33 x 25.50 = €34Therefore, £25.50 = €34

Joe's cell phone cost him $21 per month plus $3 for every 1GB downloaded. What is the limit to the number of GBs he can download to stay within his monthly budget of $30?
Answer:
3GB’s you just add 21 to 3 and keep adding 3 until you reach 30
21+3=24 24+3=27 27+3=30
Step-by-step explanation:
joe can only use 3gb of data . bill is 21
21+9+30
1gb=3
3*9=9
3(3)+21=30
3×3=$9
$21+9= $30
he can download up to 3 gbs anymore and he'll go over budget.

10 POINTS!!!!
Answer:
(z - 2) (z^2 + 9)
Step-by-step explanation:
Factor the following:
z^3 - 2 z^2 + 9 z - 18
Hint: | Factor pairs of terms in z^3 - 2 z^2 + 9 z - 18 by grouping.
Factor terms by grouping. z^3 - 2 z^2 + 9 z - 18 = (z^3 - 2 z^2) + (9 z - 18) = z^2 (z - 2) + 9 (z - 2):
z^2 (z - 2) + 9 (z - 2)
Hint: | Factor common terms from z^2 (z - 2) + 9 (z - 2).
Factor z - 2 from z^2 (z - 2) + 9 (z - 2):
Answer: (z - 2) (z^2 + 9)

Which of the following statements are true about inverse matrices?
All square matrices have inverses.
If A and B are inverse matrices, then A and B must be square matrices.
The determinant of a singular matrix is equal to zero.
If A and B are inverse matrices, then A + B = I.
If A and B are inverse matrices, then det(A)xde(B)=0
Any zero matrix does not have an inverse.
If B = A–1, then A = B–1.
B = A–1, then A = B–1. This statement is true. The inverse of a matrix is unique, so if B is the inverse of A, then A must be the inverse of B.
what is matrix ?An arrangement of integers in both columns and rows is known as a matrix. learns about matrices' components and dimensions and first presents them. A matrix is a rectangular grid with integers arranged in rows and columns.
The statements that are true about inverse matrices are:
Not all square matrices have inverses. A square matrix only has an inverse if its determinant is not equal to zero. If the determinant of a square matrix is zero, it is called a singular matrix and does not have an inverse.
If A and B are inverse matrices, then A and B must be square matrices. This is because only square matrices can have inverses.
The determinant of a singular matrix is equal to zero. This is because the determinant of a matrix is related to the linear independence of its columns or rows. A singular matrix has linearly dependent columns or rows, which means its determinant is zero.
If A and B are inverse matrices, then A + B = I. This is not necessarily true. In general, the sum of two inverse matrices is not necessarily the identity matrix.
If A and B are inverse matrices, then det(A) x det(B) = 1. This statement is almost true, but the correct statement is det(A) x det(B) = det(AB) = 1.
Any zero matrix does not have an inverse. This is because the determinant of a zero matrix is zero, and therefore it is singular and does not have an inverse.
If B = A–1, then A = B–1. This statement is true. The inverse of a matrix is unique, so if B is the inverse of A, then A must be the inverse of B.

Answer:
You will use [tex]\frac{1}{4}[/tex] cup of sugar.
Step-by-step explanation:
Given that:
A recipe calls for 3/4 cup of sugar and 1/2 cup of brown sugar.
Ratio of sugar to brown sugar = 3/4 : 1/2
Amount of brown sugar used = 1/6
Amount of sugar used = x
Ratio of sugar to brown sugar = x : 1/6
As the relationship is proportional;
[tex]\frac{3}{4}:\frac{1}{2}::x:\frac{1}{6}[/tex]
Product of mean = Product of extreme
[tex]\frac{1}{2}x=\frac{3}{4}*\frac{1}{6}\\\\\frac{1}{2}x = \frac{1}{8}\\\\x = \frac{1}{8}*2\\\\x=\frac{1}{4}[/tex]
Hence,
You will use [tex]\frac{1}{4}[/tex] cup of sugar.
The drawing below represents a 22-foot ladder with its base placed 10 feet from the bottom of a vertical wall. whatis the best value for x
Answer:
x = 62.96°
Step-by-step explanation:
From the attached figure,
Base, b = 10 ft
Hypotenuse, H = 22 ft
We need to find the value of x. We can use trigonometry to find it.
We know that,
[tex]\cos\theta=\dfrac{B}{H}[/tex]
Putting all the values,
[tex]\cos x=\dfrac{10}{22}\\\\x=62.96^{\circ}[/tex]
So, the value of x is 62.96°.

Answer:
22.74 liters
Step-by-step explanation:
GIven data
Felix's washing machine uses 6 gallons of water
we are told that A gallon is approximately 3.79 liters
Hence if a gallon is approximately 3.79 liters
then 6 gallons of water will be x liters
cross multiply we have
x= 6*3.79
x= 22.74 liters
Hence 6 gallon will be 22.74 liters

By the Pythagorean theorem, x^2=10^2+10^2
x^2=200
x=14.14
You drop a ball from a height of 98 feet. At the same time, your friend throws a ball upward. The polynomials represent the heights (in feet) of the balls after t seconds. At what time do the balls reach the same height?
Answer: The polynomial is 92 - 46t
92,92,-46,46
Step-by-step explanation:
The polynomial represent the heights (in feet) of the balls after t seconds is : -46t+92
What is a polynomial?They are mathematical expressions involving variables raised with non negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non negative exponentiation of variables involved.
The motion of both balls is a free-fall motion which means that the ball is acted upon the force of gravity only.
Therefore, the motion of the ball is a uniformly accelerated motion, with constant acceleration equal to the acceleration of gravity:
g = 32 ft / sec sq.
The ball which is thrown upward from the ground instead is fired with an initial vertical velocity , and its starting height is zero, so its position at time t is given as;
h(t) = ut - 1/2 gt²
Therefore, the polynomial that represents the distance between the two balls is -46t+92

what do you call a crushed angle ?
Answer:
A Rectangle
Step-by-step explanation:
a wrecked angle
A crushed angle is commonly referred to as a "rectangle" or a "wrecked angle".
When an angle is crushed or collapsed, its sides are no longer straight or evenly spaced, and its vertex may be shifted or deformed.
This deformation can occur in various contexts, such as in physical objects or in mathematical diagrams. The angle's original shape has been significantly changed due to external influences.
Thus, a crushed angle is commonly referred to as a "rectangle" or a "wrecked angle".
This is a play on words, as a rectangle is a shape with four right angles, and when an angle is crushed or wrecked, it can resemble a rectangle.
